I have uploaded a load of custom .wav files into /var/lib/asterisk/sounds/ and have converted them using:
for i in *.wav; do sox $i -c 1 $(basename $i .wav).gsm; done
but when I now use the, say voicemail for example, you get
"you have" click “one” click “new message” click “press one for…” click. It is like the sound files don’t end it silence, or are clipped? I have downloaded the .gsm files and they all start and end with silence and when I play them using quicktime they play fine without clicks.
Can anyone point me in the right direction?
